ROTARY-CUTTER CLEANER.

SECIFICATION forming part of Letters Patent No. 662,749, dated November27, 1900.

Application filed August 21, 1900. serial No, 27,595. .l\lo modeln Toall whom it may concern.-

Be it known that I, JOHN F. ARTHUR, a citizen of the United States, anda resident of New York, in the county of Kingsand State of New York,have invented certain new and useful Improvements in Rotary-CutterCleaners, of which the following is a specification.

In the working of metals by means of rotary milling tools or cutters itis advantageous and in many cases necessary, toproduce cleancnt work, toremove the chips from the teeth of the rotary cutter and to apply aproper lubricant thereto. This is now generally done by the use of ahand-brush to remove the chips and by the occasional application of oilto the cutters or by washing the cutters by means of a continual flow ofoil thereto. I have de: vised a simple and efficient cleaning device bymeans of which the teeth of rotary cutters and analogous tools may beeconomically kept clean and free from chips and, when desired, suitablylubricated, thus insuring the performance, by the use of such tools, ofcont-in nous, perfect, and clean-cut work, the same consisting of abrush, preferably circular in form, arranged in such relation to therotary cutter to be cleaned and mounted on a suitable axle or shaft thatits plane of movement will be transverse to the plane of rotation of thecutter and at or near a right angle thereto, with the axis of the cutterin the plane of movement ofthe brush or approximatingsuch' relationthereto, the arrangement being such that the ends of the bristles (whichword bristle is intended to cover all material employed in the activepart of the brush) will move laterally through the path of rotation ofthe cutter sidewise through the spaces between the cutter-teeth and bymeans of a direct sweeping action brush the cutting edges and faces ofthe teeth and so remove all chips and dirt therefrom. When a lubricantis to be used, it may be occasionally applied to the rotating brush, thebristles of which will hold it in considerable quantity and transfer itwithout waste to the cutting edges of the rotary cutter as they sweeptransversely across the cutting-faces. My invention, however, furthercontemplates automatically supplying oil or other lubricant to therotating brush in such quantity as to insure the requisite and properlubrication of the cutter. To this end the shaft of the brush is madehollow, provided with a suitable oil-cup, and having lateral holesextending from the central cavity to openings formed through the hub ofthe brush to the roots of the bristles thereof, the brush thus beingkept moistened or supplied with the lubricant.

To illustrate my invention, an application of my cleaning device to amachine in which roiary cutters are used is shown in the accompanyingdrawings, in which- Figure 1 shows in front elevation so much of amillingmachine with a rotary cutter acting on a gear-wheel blank as isnecessary for a correct understamling of the use and application of myimproved cutter-cleaning device. Fig. 2 is a plan view of the same,partly in section.

The rotary cutter a, shown as a gear-cutter, is for illustrativepurposes carried on a mandrel having its bearing in the traversing headI), and the wheel-blank c is suitably supported for the cutter a to actthereon as it is caused to travel over the blank, the handle (Z beingshown as the means by which the traversing head is moved.

The circular brush 6 is, as before stated, arranged to maintain a givenposition rela tive to the cutter. In this case it is shown as carried onthe end of the vertical shaftf, fitted to rotate in bearings on thebracket g, secured to the traversing head I), which carries the cuttera. Rotary motion may be applied to the shaftf and brush 6 by anysuitable means-as, for instance, the traveling belt h, passing aroundthe grooved pulley t, secured to the upper end of the shaftfand guidedthereto by the guide-pnlleysj. In carrying out the principle of myinvention it is not necessary that the plane of rotation of the brush abe at right angles to the plane of motion of the cutter a for the properaction of the brush on the teeth of the cutter, for the ends of thebristles of the brush will effectually sweep laterally across thecuttingfaces of the teeth of the cutters if the axis of the brush be setat an angle to the vertical when the axis of the cutter is horizontal,as shown. The brush need not rotate continually in one direction. Itwill, if given a reciprocating motion, practically perform the functionsof the invention as long as it moves in a path transversely to the planeof rotation of the cutter, which path may be more or less at an angle tothe cutting-faces of the teeth, and still the brush will sweep over thecutting-faces and remove the chips therefrom.

For a continuous supply of lubricant to the brush 6 an oil-cup la isapplied to the upper end of the shaftf and from which the lubricant isfed at any desired amount down the bore Z of the shaft through lateralholes therein and holes on, formed in the,hub of the brush 6, and sopasses to the sweeping portion of the brush and from such portion isapplied to the cutting edges of the cutterteeth.

Such modifications as are necessary to the adaptation of this inventionto other forms of cutters and their arrangements relatively to the workor material operated on other than shown in the drawings Will be readilysuggested to those skilled in the art of metal working, and what is hereshown is considered sufficient to fully define the nature andapplication of the invention.

I claim as my invention- 1. A rotary-cutter cleaner, consisting of abrush held and arranged to move in a plane transverse to the plane ofrotation of the cutter, and sidewise through the spaces between thecutter-teeth, and means for imparting motion to the brush to cause it tosweep over the edges and the cutting-faces of the teeth of the rotarycutter.

2. A rotary-cutter cleaner consisting of a circular brush, ashaft uponwhich the brush is mounted, a bracket or other holder for the shaftadapted to hold the brush relatively to the rotary cutter to be cleanedso that its plane of rotation will be transverse to the plane ofrotation of the cutter with the edge of the brush moving sidewisethrough the spaces between the cutter-teeth, and means for rotating thebrush.

3. A rotary-cutter cleaner and lubricator, consisting of a circularbrush, the hub of which is perforated from the central opening tothe'roots of the bristles, a bored shaft upon which the brush is mountedhaving lateral holes opening into the perforations of thehub of thebrush, an oil-cup attached to the open end of the shaft, means forrotating the brushshaft, and a support for said shaft adapted to holdthe brush so that its path of rotation will he transverse to and enterthe path of the cutting-teeth of the rotary cutter.
